Overview

• Hannover’s Sprengel Museum has extended opening four nights a week to 20:00 for its Instagram-friendly “Niki. Kusama. Murakami. Love You for Infinity” show.
• Dozens of institutions now offer at least one late weekly slot known as a “Long Thursday,” with venues like Frankfurt’s Städel and Düsseldorf’s Museum Kunstpalast open to 21:00.
• Privately run operators are leading the shift, exemplified by Berlin’s DDR Museum which opens daily from 9:00 to 21:00 and by immersive exhibitions with flexible schedules.
• Hamburg’s Miniatur Wunderland routinely runs roughly 7:00 to 1:00 to maximize access, with management citing maintenance and staffing limits as barriers to 24-hour opening.
• High demand of about 106 million museum visits annually encourages selective extensions, though staffing, costs and upkeep still constrain broader changes.
